FODDER-S'HREDDER.

s'PECIFIGATION forming part of Letters Patent No. 593,005, dated November 2, 1897.

Application filed June 5, 1897. herial No. 639,591. (No model.)

To a whom it may concern.-

Be it known that I, J OHN K. VVILDER, a citizen of the United States, residing at Monroe, in the county of Monroe andState of Michigan, have invented certain new and useful Improvements in FodderShredders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventionrelates to improvements in fodder shredders, splitters, and crushers, and particularly to that part of the mechanism which is called the shredder-head.

The object of my invention is to provide a shredder-head which can be cheaply made, cheaply and quickly renewed in the case of accident or wear, and one that can be easily changed to split or shred the stalk fine or coarse, as desired.

It consists in a shredder-head composed of independent teeth, bolts or rods passing between the teeth to hold them in position, and washers for binding them together.

It also consists in a shredder-head having a driving-shaft, a series of shredding-teeth, spacin g-washers, and bolts or rods for clamping them together.

It also consists in certain other novel constructions, combinations, and arrangements of parts, which will be hereinafter fully described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 represents a perspective view of my improved shredderhead. Fig. 2 is a vertical longitudinal section through the same, and Fig. 3 is a vertical transverse section of the said shredder head.

A in the drawings represents a drivingshaft; B B, binding washers or heads; 0 0, bolts for holding the parts in place, and D D cutting or shredding teeth.

The shaft A is of any suitable size adapted to support a shredder-head in a machine of any ordinary construction used for shredding fodder or other similar substances. The teeth I), forming the cutting portion of the shredder-head, are preferably formed of flat pieces provided with cutting edges, as at (Z d, upon its opposite ends. These teeth D are preferably enlarged at their central portions and perforated at cl to fit upon the shaft A. In making up the shredder-head a large number of teeth are slipped onto the shaft and are arranged alternately at different angles, as clearly seen in the drawings. Washers E are preferably interposed between the teeth D in order to space them at equal distances from each other. It will be apparent that by putting in washers of different thicknesses the space between the teeth maybe made greater or smaller as it is desired to shred the fodder coarser or finer. It will also be evident that when it is desired to shred fodder very finely the washers may be omitted from between the teeth entirely without departing in the least from the spirit of my invention. After the teeth and washers are placed upon the shaft A end washers B B are slipped upon the shaft A and the bolts 0 C are passed between the teeth D and through the apertures b .17 of the washers B. The bolts C G are threaded at their ends to receive nuts, as c o. By screwing the nuts tightly upon the bolts G the washers may be drawn tightly against the teeth and bind them firmly in place upon the shaft A. The washers B B may be keyed upon the shaft A orfirmly secured thereto by set-screws or other similar means after the parts of the shredder-head have been assembled. The washers may be also prevented from turning by placing them on a squared portion of the shaft or upon a squared thimble keyed or otherwise secured to the shaft.

The binding-bolts O,instead of being passed between the teeth, as shown in the drawings, may be passed through apertures in the teeth, if desired, without departing from the spirit of my invention. So, also, the bolts may, if desired, be passed through the washers E.

It will be observed from the above description that a shredder-head constructed in accordance with my invention may be made very cheaply and that the parts may be quickly assembled to form the head. The parts may also be as quickly taken apart in order to replace broken or worn-out teeth or to sharpen the same. So, also, as heretofore mentioned, by changing the thickness of the washers the distance between the teeth may be regulated to correspond with the desired cut.

Having now described my invention, what too edges to hold them in place, the said washers being entirely within the said bolts but not engaging them, the said bolts also engaging the said holding means for binding the parts together, substantially as described.

2. A shredder-head composed of independent teeth mounted upon a central shaft,means for holding the said teeth in position by side pressure and bolts passing between the teeth for holding them at the proper angle with relation to each other and adapted to engage said side holding means for binding the parts together, substantially as described.

3. A shredder-head composed of independent removable teeth, washers for holding the teeth in place by end pressure, bolts adapted to pass between the teeth and engage the edges thereof for holding them in proper place, said bolts also engaging the end washers for binding the parts together, substantially as described.

4:- A shredder-head composed of independent teeth, spacingwashers interposed between said teeth, means for binding said teeth and washers together for forming the said shredder-head, and bolts adapted to pass be tween the teeth and engage the edges thereof for holding them in proper place, substantially as described.

5. A shredder-head comprising independent teeth, said teeth being adapted to be mounted upon a shaft, binding-washers at the opposite ends of the head, bolts arranged longitudinally of the head for drawing the binding-washers together and engaging the edges of the teeth between the same for holding the said teeth in proper position, and means for securing the washers to the shaft to prevent the same from being turned thereon, substantially as described.

6. A shredder-head composed of teeth provided with central apertures adapted to engage a suitable shaft, said teeth being arranged alternately at different an gles,washers for in'closing said teeth upon each end of the head, bolts passing between said teeth and engaging their edges for holding them at the desired angles, the said bolts also engaging the binding-washers for holding the parts together, substantially as described.

'7. In a shredder -head, the combination with a suitable shaft, of independent cuttingteeth provided with apertures for engaging said shaft, the said teeth being arranged at different angles alternately, washers for inclosing the said teeth upon said shaft, bolts passing between the edges of the teeth and adapted to hold the same at the proper angle, said bolts being threaded at their ends and adapted to pass through apertures in the said Washers, nuts for engaging the ends of the bolts to draw the washers toward each other and spacing-washers interposed between the teeth, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
